API groups have the region attribute. After you create an API and select a group for the API, the corresponding region is also selected. We recommend that you select the region where your backend services are located for reducing network delay.

After you create an API group, you can bind a filed custom domain name to the group.

This API can call up to 50 QPS for a single user.
